2018 Ford E-350 Fuse Box Diagram

FUSE SPECIFICATION CHART

Power Distribution Box

WARNING   WARNING:  Always disconnect the battery before servicing high current fuses.
WARNING   WARNING:  To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.

Note:   If your vehicle is equipped with dual batteries, disconnecting the primary under-hood battery does not remove power from all circuits.The power distribution box is in the engine compartment. It has high-current fuses that protect your vehicle’s main electrical systems from overloads.If the battery has been disconnected and reconnected, you need to reset some features.   See   Changing the 12V Battery

CHANGING A FUSE

Fuses

WARNING   WARNING:  Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire.

If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components.

Fuse Types:

Callout  Fuse Type  
A  Micro 2  
B  Micro 3  
C  Maxi  
D  Mini  
E  M Case  
F  J Case  
G  J Case Low Profile
